Presentation

minimal degree	μ(G) = 26
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 6 generators on 26 points:

(7,8)(9,10)(11,12,15,16)(13,17,18,14)(19,20,22,24)(21,23,25,26);(3,4)(5,6)(19,20)(21,23)(22,24)(25,26);(4,5)(13,18)(14,17)(21,25)(23,26);(7,8,9,10)(11,13)(12,14)(15,18)(16,17)(19,20)(21,26)(22,24)(23,25);(1,2);(3,5,6,4)(7,8)(9,10)(11,14)(12,13)(15,17)(16,18)(19,21)(20,23)(22,25)(24,26)

GAP

Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:

gap> G := Group((7,8)(9,10)(11,12,15,16)(13,17,18,14)(19,20,22,24)(21,23,25,26), (3,4)(5,6)(19,20)(21,23)(22,24)(25,26), (4,5)(13,18)(14,17)(21,25)(23,26), (7,8,9,10)(11,13)(12,14)(15,18)(16,17)(19,20)(21,26)(22,24)(23,25), (1,2), (3,5,6,4)(7,8)(9,10)(11,14)(12,13)(15,17)(16,18)(19,21)(20,23)(22,25)(24,26));
